Abstract: In this paper, a single-phase permanent magnet actuator will be investigated concerning the influence of maximum ambient temperature and ambient temperature range on weight and cost. The specifications of a throttle-plate actuator for the automotive industry serve as an example. The main emphasis will be put on the different characteristics resulting from the use of ferrite magnets or NdFeB material.

Abstract: The manufacturing of advanced electronic products and components requires precise two-dimensional (2D) planar motion for surface positioning, parts assembly and component insertion. To achieve precise 2D planar motion, most of these high-performance manufacturing machines use cascaded X-Y tables with rotary motors and rotary-to-linear mechanical couplings. Though this is the most widely-used method, it has disadvantages of complex mechanical structure, frequent mechanical adjustments, high manufacturing/maintenance cost, and low reliability. This paper proposes a novel 2D Variable Reluctance (VR) planar actuator to replace conventional X-Y tables. Unlike existing planar motors based on permanent magnet synchronous drive, inductive drive, and open loop stepper drive, this paper proposes a 2D actuator based on variable reluctance driving method. The proposed actuator has a very simple and robust structure. It has very few mechanical parts, and it can be manufactured easily. A prototype actuator was fabricated. Preliminary characteristics measurements confirmed that the proposed structure is very suitable for high-performance planar drive in industrial automation.
